Do the words ‘solemnly’ and ‘seriously’ collocate with ‘apologise’? Do the words ‘solemnly’ and ‘seriously’ collocate with ‘apologise’? Any other words that collocate with ‘apology’, ‘apologise’ and ‘apologetic’? 1) Joseph apologised to his boss solemnly/seriously. 2) Benjamin has to make a solemn/serious apology to his friend for causing her a lot of trouble. Looking foward to your reply. Thank you in advance.
